Gumdrop Dome

Materials needed:

          30 toothpicks                                              

          10 gumdrops

 

 

Hypothesis: 

How many books do you think your gumdrop dome can support?

 

 

Procedure:

 

1.     Use 5 gumdrops to connect 5 toothpicks in a ring.  This is your base.

 

2.     Use 2 toothpicks and 1 gumdrop to make a triangle on one side of the base.  In the diagram below, each new step is highlighted in yellow.

 

3.     Repeat this all around the base until you have 5 triangles.

   

 

                            

 

 

4.     Use toothpicks to connect gumdrops at the tops of triangles.

                               

5.     Push 1 toothpick into each of the top gumdrops.

 

 

6.     Use 1 last gumdrop to connect these toothpicks at the top.

 

      7.   Let the dome dry overnight.
